Abstract: An equipment and method of manufacturing an amplifier utilizes different injection molding machines to respectively manufacture an external case of an amplifier by using unlimited kinds of material to increase the connection between a diaphragm and a suspension, reduce the cost and enhance the speed of manufacture and the utilization rate of producibility tremendously.

Abstract: An improved structure of amplifier, the amplifier consists of a frame, a base fixed at the bottom of the frame, one or more than one magnet, a spacer, a T-shaped iron, a package component containing one or more than one damper, a cone paper, a heat sink, a rubber edge, a dust cap, a voice coil, a fixed tube, the package component is placed inside the frame, the frames is featured by its one-body structure which is produce by injection molding and made of rubber material.
